Explanation:
Voltage of a battery is defined as the electric potential energy per charge. It is a scalar quantity. It doesn't has any direction. As per Ohm's law, voltage is given by the product of current and resistance. Its SI unit is volts.
It is responsible for making current to flow in the circuit. In a series combination of resistors, the potential difference across every resistor divides while in parallel combination of resistors, the potential difference across each and every resistor remains the same.
Hence, the correct statements are :
b. It is measured in volts.
d. It's what makes current flow in a circuit.
e. It is related to current and resistance by Ohm's Law.
